It has two testing holes, you can test two spark plugs meanwhile and and if you suspect any spark plug works improperly you could compare and test to make accurate judgment.
Usage: test spark plug performance and ignition strength
Application range: 12V Gasoline vehicles car spark plugs
Widely application: 100V-240V input voltage .
Test principle: In automobile ignition system, the high-voltage ignition coil generates a high-voltage (10000 volts or more), and the spark plug diverts it form high -tension ignition coil into the cylinder engine, spark between the spark plug electrodes will ignite the mixture. The JF109 could tell the good spark plugs from the bad by the strength of the spark.
Function: support to share battery test results and generate reports
Using international conductivity testing technology, it can easily, quickly and accurately measure the actual cold start current capability of the vehicle starting battery, the health status of the battery itself, common faults of the vehicle starting system and charging system, and provide help for maintenance personnel to quickly and accurately find out problem, so as to achieve rapid repair.
Support analysis and reading of important car data such as voltage, internal resistance, cold crank amplifier, battery health and state of charge. It provides accurate results, calculating the cold crankability and aging of the battery, making car repairs faster and more accurate.

The 3 modes can be switched at will. The mode switch is operated by the physical button on the main body of the electronic pen. Press and release the button to cycle through the three working modes.
The working range is 5-30V, not more than 30V
Both positive and negative voltages can be measured. For the load plug, the probe directly connected to the clip can be combined with the probe of the test pen to directly perform load simulation measurement, which is convenient for fault diagnosis.
Do not approach high-voltage lines to prevent LEDs from being broken down by high voltage.
Connect the device correctly to the spare battery red clip to the positive pole and black clip to the negative pole to detect battery information or battery leakage detection
Widely used in automobile and motorcycle maintenance industry
